Curvature of space-time relative to mass works pretty well for most folks.
Yes, but what ‘causes’ the curvature?..................
Mass. Or turtles.
It is the dawn of time.
This earth we know so well is a smoldering, inhospitable place.
No plants grow, no creature can survive.
The hard, implacable rocks that form our mountain ranges are being crushed and folded by forces that will take millions of years to shape.
These are the forces!
This is the power that drives the hand that drinks ‘Treadmill’, the mighty lager, with the world’s first great taste of fish!
“fudge factor” i.e. we don’t know anything except that it makes the equations work....
What is mass?..............
There are two competing theories: WIMP’s vs. MACHO’s. Weakly Interacting Massive Particles are hypothetical ghost particles that (besides gravitationally) interact only weakly or not at all with normal matter, sort of like the neutrino. But unlike the neutrino, they are massive enough to clump around galaxies. The room you’re sitting in could be filled with them but there is no way to detect them.
MAssive Compact Halo Objects are things like black holes, neutron stars, even brown dwarfs. But they would have to be in great enough numbers to account for all the mass of dark matter.
So far, ironically, WIMP’s seem to be winning out over MACHO’s as the leading theory.
The existence of Dark Matter was actually discovered by Fritz Zwicky back in 1933, when he noticed gravitational interactions between galaxy clusters that their visible mass couldn’t account for. He was an underrated scientist then and today.
If the universe is 13.8 billion years old, then Earth would need to be 13.8 billion - 0.8 billion (780mil) = 13.0 billion light years away from the big bank to intercept the light.
I've been told that inflation figures into it. But still Inflation plus the speed of the galaxy away from the big bang would have to equal (13.0/13.8)=94% of the speed of light for us to currently be intercepting light from 780 million years after the big bang.
Possibilities:
What is pedantry?
The earth is not the same age as the universe.
Sounds like a lot of speculation.
Ding..ding...ding
You win the post for this thread
‘Dark Matter’ is as real as AGW.
Attention to detail.................
Supposition.
Modern cosmologists invented dark matter to save the Standard Model, according to which, the universe should have flown apart by now.
Instead of questioning the fundamental validity of their underlying theories, they invent unobservable, unmeasureable phenomena that can't be checked or tested, to explain observations their theories have failed to predict.
Which makes it worse.

Was there a Piper at the gates of dawn?
Exactly!
When actual observations falsify your cherished theories, the gods of Scientism command you to invent fairies and unicorns to explain it away.
